Association between pre-pregnancy body mass index and gestational weight gain and perinatal outcomes in pregnant women diagnosed with gestational diabetes mellitus: The Japan Environment and Children's Study.

ABSTRACT:

Aims/introduction

We investigated the association between gestational diabetes mellitus (GDM) and perinatal outcomes stratified by pre-pregnancy body mass index (BMI) and/or gestational weight gain (GWG).

Materials and methods

Data from the national birth cohort in the Japan Environment and Children's Study from 2011 to 2014 (n = 85,228) were used. Japan uses the GDM guidelines of the International Association of Diabetes and Pregnancy Study Groups. The odds ratios (ORs) of perinatal outcomes were compared between women with and those without GDM.

Results

The OR (95% confidence interval) of having a small for gestational age infant in the GDM group with a pre-pregnancy BMI of ≥25.0 kg/m² and insufficient GWG (<2.75 kg) was 1.78 (1.02-3.12). The OR of having
